The role of root allometry and root overlap in vegetation pattern formation
Jelle van der Voort, Ricardo Martinez-Garcia, Arjen Doelman
We investigate how root allometry and below-ground root competition due to root overlap affect the conditions for pattern formation in non-local scalar vegetation models. We start…
Fixation probabilities for multi-allele Moran dynamics with weak selection
Ian Braga, Lucas Wardil, Ricardo Martinez-Garcia
Fixation probabilities are essential for characterizing stochastic evolutionary dynamics, but analytical results remain limited mainly to systems with two competing types. We devel…
Extinction and persistence criteria in non-local Klausmeier model of vegetation dynamics on flat landscapes
Maciej Tadej, Ricardo Martinez-Garcia, Michael Hecht
This paper investigates the dynamics of vegetation patterns in water-limited ecosystems using a generalized Klausmeier model that incorporates non-local plant dispersal within a fi…
Vegetation pattern formation induced by local growth outpacing susceptibility to non-local competition
Jelle van der Voort, Ricardo Martinez-Garcia, Arjen Doelman
In this work, we present and analyze a general framework for vegetation dynamics in arid and semi-arid ecosystems in which non-local interactions are purely competitive. The genera…
